Robyn and Spears both had success in the US in the '90s with songs written by Max Martin. However the Swede returned to Stockholm after a tour with the Backstreet Boys, suffering from exhaustion.
The popstar claimed she was pleased with her decision to leave the US, because success had come at too young an age.
Talking about Spears, she told The Sun: "We are different. Success did come to me very young but I managed to take time off, which I think was a very good move.
"I’m proud of the fact I decided to leave the US after my initial success and figure out who I was going to be. I think that was the healthy thing to do.
"Maybe it does show intelligence on my side but I knew that all that mattered was the music and I needed to be in a place where no one tells me what to do or how to do it.
"It’s always been about enjoying what I do and that’s the basis of all the decisions I make."
